MOLDING DEVICE.

SPECIFICATION forming-part of Letters Patent No. 590,039,dated September14, 1897. Application filed January 7, 1897. Serial No. 618,22Q. (Nmodel.)

To all whom it 7120 concern:

Be it known that I, EDWIN FABIAN, of St.

Paul, Ramsey county, Minnesota, have invented certain Improvements inMolding Devices, of which the followingis a specification.

My invention relates to improvements in molding devices; and it consistsof the features of construction hereinafterparticularly described andclaimed.

In the accompanying drawings, forming part of this specification, FigureI is a plan view of a molding-table and the patterns working therein.cal section of the same. Fig. 3 is a vertical cross-section of the same.Fig. 4 is a sectional detail of a link filled with a core to constitutea matrix, and Fig. 5 is a partial plan view of the drag of amolding-flask having the molds formed therein.

In the drawings, A represents the moldingtable, adapted to receive alink 2, which is designed to be connected with a series of lVorkingthrough similar circularly-curved openings in the top of the table isthe pair of similar patterns 10, oppositely disposed, as shown, so as tohave their adjacent ends projected upward through the link 2, thepatterns corresponding in curvature and dimensions to that of theconnecting-links to be formed.

The patterns are operated by means of their downwardly-projecting arms11, which are connected together by the tension-sprin g 12, thus servingto hold the patterns with their adjacent ends upwardly projected, as

shown in Fig. 2, in which position they stand approximately level withthe top of the link 2.

Pivoted in the table A is the pair of operating-levers C, the fulcrumends 13 and 1a of which stand between and in engagement with the arms11. By the closing together of the handles of the levers the-fulcrumends are terns are then withdrawn by operating the Fig. 2 is alongitudinal vertiz,

lever O, leaving corresponding openings through the core. When thesematrix-links have thus been supplied with cores, they are placed inposition in the cavities or pockets 5, previously formed in anysuitablemanner in the drag of the flask. These pockets are connected bythe channels 6, which conform in shape to that of the links to beformed. These channels are connected to the gate of the flask by meansof ports 7. The cope of the flask has similar cavities or channels, sothat when the links are all in place in the pockets 5 and the cope is inposition upon the drag the channels 6 constitute molds for the links tobe formed,'each having a port 7, the

openings in the cores of the matrix-links being in line with the severallink-molds. The

molten metal then beingpoured into the flask fills the molds andconnects the matrix-links by the links thus formed.

The flasks are all of such dimensions as to make up any suitable lengthsof chain-sections, the ends of which are connected together by fillingthe end links with cores and placing them in the flask to be similarlyconnected by new links. Thus a chain may be built up of any desiredlength.

I claim- For the manufacture of cast-metal chains, means for formingcores in the several links to be connected into a chain, consisting of asuitable molding-table adapted to support a link in substantiallyhorizontal position thereon, the pair of oppositely-disposed, similar,circular patterns working in a vertical plane through thetop of saidtable,the dimensions and curvatures of said patterns corresponding tothose of the ends of the links to be formed, and being so disposed as toproject their adjacent ends upward through the link laid upon saidtable, the depending arms upon said patterns, the spring normallyholding said arms drawn together so as to project the adjacent ends ofthe patterns upward, and the pivoted levers engaging said arms andadapted to withdraw said link. 1

In testimony whereof I affix my signature in presence of two witnesses.

EDWIN FABIAN.
